The most common foods containing titanium dioxide are chewing gum, candies, pastries, chocolates, coffee creamers, and cake decorations (1Trusted Source, 3Trusted Source).
Different from the general zinc barbed rope, high zinc barbed rope surface zinc content is very high can reach the former 6-8 times, so in the service life also has a great advantage, ordinary products three or five years began to corrosion and the latter will take longer to change. Stainless steel barbed rope is in the material aspect of protection, so the durability is also better, these two products are long in the service life, but in the price is high.
And the role of wire mesh in the exterior wall plastering if from an Angle to sail a method of anti-falling, the role of anti-cracking is relatively small, because of the problem of orientation; And about the external insulation system is used in the tile veneer, as for the role should also be anti-drop followed by anti-cracking, so the grid should be selected 10×10×0.6, these are some experience selection, grid conversion from the national provisions of the wire mesh standard, choose the level of steel conversion.
But there are some necessary precautions in the production of galvanized wire. Remove all tools and piles on the work site and equipment that hinder activities, and slowly put the wire into the cylinder during pickling to prevent acid splashing on the body. When adding acid, the acid must be slowly poured into the water. Do not pour water into the acid to prevent acid spillage and injury. Workers should wear protective glasses when working. Then in the handling of wire and other items, it is strictly prohibited to push hard.
Large hexagonal net is called stone cage net, mainly used for mountain protection, hydraulic construction, etc. Small wire hexagonal net is used as a good breeding material, the twisted flower hexagonal net in the welding of the iron frame get on the hexagonal net burning welding coops, pigeonholes, rabbit cages and other cage, hexagonal net is the best breeding material with the net.
There are two kinds of use, namely slope protection hook mesh, coal hook mesh, mining hook mesh, coal mine support network, roadway support network. The height of the outer rail of the pavement or seat belt should not be less than 1.10 m. The net distance between balustrade members shall not be greater than 140 mm, and horizontal rail shall not be used. Hook mesh planning is necessary to be safe and reliable, anchor should be installed on the basis of the railings, its strength should meet the requirements of the standard.
Steel wire mesh by its own unique advantages in construction occupation, reinforcement anti-crack occupation is indispensable reinforcement anti-crack data, high product error is small, mesh mesh uniform, welding firm, strong acceptance, not easy to deformation, steel wire mesh in different fields have different called, in bridge engineering construction people call it soft reinforcement.
Some customers are more concerned about quality problems, so for the service life is more important, barbed rope factory will generally recommend the use of high zinc barbed rope or stainless steel barbed rope.
The use of electric welding mesh is very wide, can be used in many places. In the field of construction, especially the wall crack, has played a very important role, the traditional construction, is to put on mortar directly onto the wall, after such a long time, will appear fall off and fracture phenomenon, in order to prevent the occurrence of this phenomenon, must use welded wire mesh before rendering, welded wire mesh is fixed to the wall, above the plastering construction, Can ensure that the wall level for a long time, not easy to crack phenomenon.
The temperature of large roll galvanized wire should be controlled at 30 to 50℃ during electroplating. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used. Continuous production does not need heating, but needs cooling. Cooling can be in the groove side row thin wall plastic pipe, through the flow of tap water cooling, can also be used as a titanium pipe temperature control device.
